ES-562/564U
COMBINATION CLOCK/TIMER
OPERATION AND MAINTENANCE MANUAL
The ES-562U/564U is a combination six digit time-of-day Clock / 100 Hour Up/Down Timer. The ES-562U
Clock displays time in 12-hour format; the ES-564U Clock displays time in 24-hour format. The clock and
timer modes operate independently – Clock and Timer operations do not affect each other. When the unit
is powered up it is in Clock mode.
Five control switches are provided, accessible on the top of the case (standard) or on the front panel
(option P). The functions are TIMER, UP/DOWN, SET/STOP, SELECT/RESET and CLOCK. Momentarily
activating the CLOCK or TIMER function will latch the unit into the selected mode, displaying the CLOCK
or TIMER data on the .56” yellow LED display. The other three switches are mode-dependent.
Setting the Clock is accomplished by holding down the CLOCK button and using the SET and SELECT
buttons. Hold the CLOCK button down and press the SELECT button. This causes the Hours-digits to
flash and allows them to be set by pressing the SET button until the hours agree with the time being set.
Continue holding the CLOCK button down and press the SELECT button again, enabling the Minutes-
digits to be set in the same manner. The same procedure applies for setting the Seconds-digits and they
should be set slightly ahead of real time. (Seconds are “synchronized” after the Calendar is set.)
Set the Calendar to the correct date in the same manner. The Calendar should be set to the correct date
because the units automatically correct for daylight savings time. To turn this feature off, refer to the layout
on page 6. Month is set first, followed by day and then year. After the date is set, press the SELECT
button one more time to stop the digits from flashing. At this time, the seconds can be synchronized to real
time by pressing and holding the CLOCK and SET buttons until real time matches the time set on the
display. When the SET button is released, the unit begins counting from that point. Errors made during the
setting procedure can easily be corrected by selecting the digit-pairs in need of correction. Set them, as
above, by pressing the SET button until the proper number is displayed. Continue selecting until all digits
are stable (not flashing).
The TIMER can be preset in a similar fashion. Press and release the TIMER button. If the TIMER is
counting, press the SET/STOP button to stop it. The timer is preset just like the CLOCK, except that the
TIMER button needs to be continuously pressed while setting. In order to store a manually preset time in
memory, either the UP button or the DOWN button must be pressed after setting the timer to the desired
preset time.
The UP/DOWN switch starts the TIMER counting up or down. The SET/STOP button, if pressed alone,
stops the TIMER. The SELECT/RESET switch, if pushed alone, acts as a reset/preset switch. The first
time it is pressed, the timer is reset to 00:00:00. If pressed again (within 5 seconds) the timer is set to the
last manually preset time. If the timer was counting up or down before being reset, it continues to count in
the same direction.
If the unit is ordered with option “R”, remote control inputs are provided on a rear-mounted 9-pin
connector. A short to ground is required to activate the desired function. The optional relay contact closure
on the Hour or Hour & Half-Hour is also accessible on the connector. The contacts are rated at 10 watts
maximum resistive load, 500 mA maximum switching current.
